To'all whom-it may concern.

Be it known that I, CHARLES Vmmmr Warren, aici'tizenof the" Republicof Switzerl a lid, residing at St;- Gallen, Switzerland, have lllVGl'l'tGlZhCCTUb'lILllGW and useiiul Improvem'ents in- Embroidering Machimes; and I do hereby dccla're'theiollowing to-be a frill=;clear,-ahd exact description of the inven tron; i suchas; will enable 1 others skilled in tlre art-to which ifiappe'rtaeins to make-and use the same,"-rcfeifence beingrhad to the ac cmnpanyingdrawings and to letters or fig arcs of 'referenee marhed thereon, which form a part of this specification.

This invention relates to a device for transferring cokirs to 'a' piece offabric framed in an embroirl'cring'machine;

The objectof 'th'einvention is to provide a device of this kind provided with members adapted to'pieree through the fabricand a color ribbon-and to' trausfer the color from the ribbon to the-iabrie iH-Whieh aLcari-ier for color-ribbons is made of flat superposed casings adaptedto act as guides for the ribbons and inov'ide'd oirthe level of eachcolor ribbon with" holesarranged at'a distance from one anothercorresponding tothe repeatof the embroidering machine, the piercin g members being adapted to be movediuto said-holes and e the ribbon carrier being adapted to be'adjasted =in such= a manner, that the casing containing-the required colorribbon can-be brought 'on a. level with the piercing members.

This invention will now be more particulady-described with-referenceto the aecom pauying (Ira-wings, whiehillustrnte several constructional examples ofthe invention.

Referring to the figures, 1 denotes a standard 'of an embroidcring machine; 2 is the frame of the machine. 3 are shuttle tracks mounted on a bar 7. 4 denotes the needles. 5 the perforators and G the punches.

To the shuttle bar 7 are fixed U-shaped holders Edistrihuted over the whole length ofl'hc machine. The holders 8 carry angle pieces iladapted to be moved transversely with regard to the fabric 10 st rcl'ehcd in the frame 2 of the machine. Each angle piece 9 carries a. vertical slotted bar ll arrangcd near the fabric 10 to he embroidered; on each bar'll is mounted a flat bar 12 capable of being adjusted and having a fork-Shaped top end. A-pin 13 of the flat bar 12 extending through the slotted har ll guided in a slot M'o'fa lever 15. The latter is fixed to a shaft 16 carried by the holder 8. The shaftlll carries also alover l7.

Thc'levers 17'are connect ed by means of a rod 18. To the end of the rod 18 facing with regard to the drawings the right hand side of the machine. c. the side on which is mounted the driving shaft 19, is fixed a tension member 20 connected at the other end to a hand lever 21. Lever 21 is pivotall v mounted on a support 22 fixcd to the standard 1 of the machine and it is adapted to engage into a toothed segment 23. A tension spring 24. which is connected at one end to the rod 18 and at the other end to a fixed pa rt of the machine. exerts constantly a pull upon the member 20' and has the tendency to keep the that bars 12in their lowermost position- On each support 8 rests 'a slide member 24 provided with an inclined surface 25 (Fig. 5). 26 denotes a bolt fixed to the angle piece 9 adapted to engage that side of-the slide-member 24 which is provided with the inclined surface 25. A. tension spring 27 connected at one end to the holder 8 and at the other end to the angle piece 9 presses the bolt 26 constantly against the slide member 24 The slide members 24 are connected by means of straps 28 and they are acted upon by tension springs 2.). i

To the slide member 24 lying nearest to the driving shaft 19 is fixed a. tension member 30 connected to a hand lever 31. The hand lever 31 is pivotally mounted in the same manner as lever .21, on the support 22 and it is adapted to engage into a toothed segment 32 of the support 22. The member 30 is constantly tensioned by the s rings 29.

The forleshapcd ends of tlie flat bars 12 support a carrier A (Figs. 4, 3, 6) having the form of a flat bar and extending over the wholelength of the machine. The carrier A is provided with three superposed flat casings, each of which acts as a guide for a colouribbon 33 passing through it. .The carrier A (Fig. 11) consists of two strips of sheet iron 34, 35. Asshown in Fig. 11, the

' strip 34 is provided with cranked portions forming partition walls between the middle casing and the two outside casings; extending from one side-wall of the middle casing to the side of the carrier lying opposite said side-wall and forming on this side the sidewalls of the outside casings. This strip 34 is bentnear the upperaud lower ends of the carrier A at right an les, thus forming the outsidev end walls of the outside casings. As the strip 34 is bent at second time at right angles it forms also the other side walls of the outside casings. The ends of this strip 34 are connected to the side-wall of the middle casing first referred to. The second side wall of the middle casing is formed by the stri) of sheet iron 35 fixed to the side walls 0 the sheet iron strip 34 which lie on the same side of the carrier A. Each of the casings formed by the sheetirou strips 34,35 is provided with a plurality of holes 30, the distance between these holes corresponding to, the repeat of the embroidering machine or distance between corresponding portions of successive patterns.

To each of the two outside supporting rods 37 for the shuttle bar 7 is fixed a support 38. To each su port 38 is-fixed a shaft 39 (Figs. 7 and Si on which is loose a ratchet wheel 40. Pine provided on a threepart roller 41 carrying the color-ribbons and mounted on the shaft 39 are adapted to engage into said ratchet wheel 40. 42 denotes a spring adapted to exert a brake ac tion upon the rotatable roller 41. Two pawls .43, 44 are also adapted to engage into the ratchet wheel 40, the pawl 43 being pivotally mounted on the support 38 and acting as a locking pawl. The pawl 44 is mounted on a lever 45 pivotally connected to the support 38 and it. is adapted to act as a feed pawl. Lever 4-5 is acted upon by a tension spring at} and it is also (ItllllltXjttttl to a lever 4:9 mounted on a shaft 48 by men us of a tension membe 47 passingaround il guide roller or rollers [.10 on the machinr frame (Figs. 2 and Ill). The pawls 43. t! are adapted to be set in and out of 01mm tion. The ribbons 32' carrying dillercnt mlors are secured to the single parts of the rollers 4-1. 50 denotes guidcwollcrs for the color ribbons arranged between the rollers 41.

48 is a shaft for actuating the pcrlorators and punches provided in connection with each needle-row of the cmbroidcring mat chine. To that end of each of these shalt. 48 which is arranged above the driving shaft 19 is fixed a lever 51. The levers 51 are connected by means of a rod having a fork-shaped lower end. The lorloshapcd end of the rod 52 carries a pin 53. On the pin 53 is loose a roll 55 adapted to be moved along this pin 53 by means of a forlclike lever 54 (Fig. 1). tion of the lever 54, the roll 55 cooperates either with a round disk 56 or a cam disk 57 of the driving shaft 19, thus actuating either the perforators or punches of the machine.

WVhen the hereinbefore described color transferring device is set into the inoperative position, the hand levers 21 and 31 are in the position shown in. Figs. 1 and 2, the carrier A for the color-ribbons being in its lowermost position, Where it is situated at a certain distance from the fabric 10 to be embroidered (Fig. 6). While the cmbroidering operation is proceeding, the shaft 48 remains stationary. the roll 55 resting on the round disk 56.

When it is desired to transfer color to the piece of fabric to be embroidered the lever 31 is at first moved in the direction of ar row 58 (Fig. 1), so that the slide pieces 24 are caused to engage with their inclined surface 25 the bolts 26, the angles pieces 9 being thereby moved toward the fabric 10, which in turn move the ribbon carrier A, from its position flush with the faces of the shuttle tracks 3 so as to clear the upper portions of said tracks that overhang the shuttle bar 7 an extent about equal to the thickness of the carrier. The ribbomearricr A is thus moved close to the fabric 10. Here upon lever 21 is also moved in the direction of the arrow 58. so that the carrier A is raised between the piece of fabric 10 and the shuttle tracks 3.

By adjusting the lever 21 in a suitable manner with regard to the toothed segment. the carrier A for the C(llOF-lll'JbOllS can be raised such an amount. that the ribbon 33 carrying the desired color is brought on a level with the punches 6. The roll 55 is then adjusted in its turn in such a manner,
